According to The Defiant, Myriad Markets, a prediction market platform on the BNB Chain, released an incident report confirming that one of its internal administrator wallets used for automatically creating and adjudicating markets was hacked. On October 26th, the attackers forcibly adjudicated market results and cashed out, affecting 10 prediction markets including the OpenAI and Anthropic IPOs, the Base 2026 token launch, and the US midterm elections. Myriad subsequently revoked the wallet's access and announced the invalidation of the 10 affected markets, promising that all funds had been recovered and the attackers had not successfully withdrawn the funds (although on-chain data showed the funds had been transferred to other addresses). The platform will automatically refund funds to both long and short positions based on the "last traded price before the attack" (deducting any fraudulently claimed bonuses), and users do not need to manually file a claim. The vulnerability originated from a leak of a backend third-party library several weeks prior. https://www.(wublock123.com)/news/myriad-markets-hacked-10-markets-cancelled-funds-recovered-70825
